Crystal Structure and Characterization of a Double-helical-chain Coordination Polymer Zinc Complex Constructed by Flexible Dicarboxylate Ligand 2-Nitro-benzene-1,4-di(oxyacetate) and Rigid 2,2′-Bipyridine Ligand
A novel double-helical-chaincoordinationpolymer [Zn(nbdoa)(2,2′-bipy)(H2O)]n constructed by flexible2-nitro-benzene-1,4-di(oxyacetate) ligand and rigid2,2′-bipyridineligand was obtained by hydrothermal reaction. The crystalstructure demonstrates that there is a double-helical chain with an inner channel running parallel to the helix axis without any interpenetration, which is connected to network
一种新型双螺旋链配位聚合物[Zn(nbdoa)(2,2'-bipy)(H2O)]n,由柔性2-硝基-苯-1,4-二(氧乙酸)配体和刚性2,2构成通过水热反应获得'-联吡啶配体。晶体结构表明存在一个双螺旋链,其内部通道与螺旋轴平行,没有任何互穿,通过 π-π 堆积和氢键相互作用连接到网络。热分析表明无限螺旋结构在高达 536 K 的温度下是稳定的。研究了发光特性,该配合物在室温下以固态显示出光致发光。
Synthesis, Crystal Structure of 1-D Double-helical Chain Manganese(II) Coordination Polymer Constructed by 2,2′-bpy and Flexible Dicarboxylate Ligand with Strong Fluorescent Emission
A new coordinationpolymer [Mn2(nbdoa)2(2,2′-bpy)2]n was obtained by hydrothermal reaction, which was constructed by 2,2′-bpy and flexibleligand2-nitro-benzene-1,4-di(oxyacetate). The crystalstructure reveals that there exists 1-D double-helical chain, which is connected to 2-D network via π-π stacking interactions. The thermal analysis shows that the complex begins to decompose at 567 K. The luminescence
